The file for sale here includes instruction for two lengths, as well as how to vary it to the amount of yarn you have, and detailed information on how to graft on needles.
approximately 50 yards / 50 meters DK or light worsted weight yarn in each of 8 colors (C1, C2, C3, C4, C5, C6, C7, C8), for a total of 400 yards / 400 meters.
crochet hook in same size as needle for provisional cast on (optional)
In my opinion, MadelineTosh DK Twist knits more like a worsted weight than a DK, so please consider that when substituting.
Initially, I thought I had full skeins of the Tiny Twists, but found that four were shorter, 30 yard, mini-minis. This pattern is perfect for irregularities in yarn amounts. Size of stripe sections and final circumference will vary with different amounts.
Skills Required: Casting on provisionally, knitting in the round, increasing and decreasing, grafting.
